hospital grade or commercial grade receptacles ?

OK, the pre-amp and the CD player it is, rather than the amps.

Is this the same Irvrobinson who said, "Don't waste too much money on powercord-related stuff. Save your money for better speakers, acoustical treatments, amps, and source components (probably in that order). Those are the things that make a difference. Use your head and reason, don't just read advertising and bogus magazine reviews. How could an outlet provide such a superior connection that water boiled 20% faster? That's poppycock. Put on your thinking cap."

Tbg, I have no intention of buying a power cord. My wife wanted to see if she could hear a difference. She knows I think she's wasting her time, but she read some of the high-emotion responses to my posts and wants to hear for herself. Local dealers are willing to lend out cables, and I'll just take them up on offers they make anytime I go shopping. It's no big deal.

Like the quote said, put on your thinking cap. And, like Albert, take a reading lesson, then read the posts. I think differences in power cables and outlets, cryo'd or not, are an illusion, and nothing posted here - NOTHING - has changed my mind a bit. I've experimented and heard nothing, and that's because there's no difference to hear. I'm indulging my wife's curiosity, nothing else.

Contrary to some here, Robin, I don't really care if you hear a difference (or not), If your wife does (or not) or if you buy these things (or not). Your mentality is messed up so you'll be like those guys that theorize belt drive TTs sound better.

I've seen the face of a friend like you change as I replaced the stock power cord in his CD player for a cryo'ed Absolute Power Cord.

This thread is a very entertaining read, I have to say. However, I think some people may be getting confused here. This whole thing about "music" cannot be explained by science. We are talking about RE-CREATING pre-recorded music through audio equipment here, not creating original music. It is pure science and nothing else.
